Questions
How big is the ESP1 PCB?
It measures 29.1 × 39 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ESP1 use?
17 parts, built around the ESP32-S2-MINI-1-N4 and LM1117-3.3. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the ESP1 KiCad files?
From the WilliamDahlen/Bitraf-kicad-workshop repository on GitHub, at the commit this page was made from: the board is ESP1.kicad_pcb and its schematic ESP1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESP1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask WilliamDahlen before reusing the design.
